反応手順
In a similar manner, 0.96 gram (0.005 mole) of 3-amino-5,6-dichloropyrazinaldehyde, 0.08 gram (0.005 mole) of benzoic hydrazide and 100 milliliters of ethanol were mixed together and refluxed for 10 minutes to obtain a benzoic acid 2-[(3-amino-5,6-dichloropyrazinyl)methylene]hydrazide product. The product was recovered and recrystallized three times from ethanol to obtain yellow crystals which after drying 2 hours at 100° C. had the following elemental analyses.
